At the Casual Connect conference in Seattle, Q-Games announced that its popular PSN title PixelJunk Monsters will make its way onto social networks as a free-to-play title.

This new version will retain the same basic tower defense gameplay as the 2008 original, but will adopt a few changes to better suit the new platform.

In the free-to-play version of the game, enemies will now move along a single, pre-determined path, and players can now plant seeds to create new locations for towers, reports Shacknews.

The game will also feature a new grid-based level map instead of a linear progression system, and players will slowly accumulate an inventory of shovels that they must use to unlock new stages and locales on the map.

Like in the original game, players will be able to compete for high-scores on leaderboards to make use of the game's social framework, and other social features have yet to be determined. Q-Games did not confirm whether co-op will make it into this version of the title.

The company did not specify which social networks PixelJunk Monsters will be available on, but noted that it plans to release the game later this year.
